cost_path_orthogonal_cpp function

(C++) Orthogonal Least Cost Path

Computes an orthogonal least-cost path within a cost matrix. Each steps within the least-cost path either moves in the x or the y direction, but never diagonally.

cost_path_orthogonal_cpp(dist_matrix, cost_matrix)

Arguments

• dist_matrix: (required, numeric matrix). Distance matrix between two time series.
• cost_matrix: (required, numeric matrix). Cost matrix generated from dist_matrix.

Returns

data frame

Examples

#simulate two time series
x <- zoo_simulate(seed = 1)
y <- zoo_simulate(seed = 2)

#distance matrix
dist_matrix <- distance_matrix_cpp(
  x = x,
  y = y,
  distance = "euclidean"
)

#least cost matrix
cost_matrix <- cost_matrix_orthogonal_cpp(
  dist_matrix = dist_matrix
)

#least cost path
cost_path <- cost_path_orthogonal_cpp(
  dist_matrix = dist_matrix,
  cost_matrix = cost_matrix
)
